Cebu, Phillippines
A day pass to an island whose reef was closed to fishing in 1974 and then measured for fifty years, and whose famous sandbar is rebuilt at the opposite end of the island when the monsoon turns.

A day pass for Sumilon, the small island off the southern tip of Cebu, reached by a short crossing from Oslob. The pass covers the Bluewater resort's day-use side of the island; the rest of it is a protected reef with rules of its own.
In 1974 a university marine laboratory persuaded the local authority to close part of this reef to fishing. It was the first protected area of its kind in the Philippines, and because a research station kept measuring what happened, it became one of the longest-running experiments in marine science.
The finding that mattered was not what happened inside the closed zone. It was what happened outside it. Fish grew larger and more numerous within the boundary, spilled over into surrounding waters, and catches around the island improved for the fishermen who had given up access to it.
Then enforcement lapsed in the 1980s and fishing resumed inside the reserve. The stocks fell away within a few years, and the surrounding catch fell with them. When protection was restored, both recovered. That sequence, measured rather than argued, is why this island is cited in fisheries policy on the other side of the world.
The white spit that everyone comes for is not a fixed feature. It is a bank of loose sand shaped by the prevailing wind, and when the monsoon reverses, the sea rebuilds it at the opposite end of the island.
So its position, length and shape depend on the month you arrive, and a picture taken in one season is a poor guide to the other. In some conditions it is a long tongue of dry sand you can walk out along; in others it is mostly submerged at high water and reappears as the tide drops.
The island has two characters. One part is resort infrastructure: loungers, showers, shade, somewhere to eat, a beach that is maintained. The other is a sanctuary where swimming is zoned, standing on coral is forbidden, and the reef is patrolled.
The pass is for the first of those, with access to the water. Snorkelling here is easy, near-shore and shallow, and the interesting ground is closer in than people expect.
The crossing is short but open, and it is the sea state rather than the distance that decides comfort; mornings are usually calmer.
There is no shade on a sandbar and the light comes back off both the water and the sand, so people burn there faster than anywhere else on the island. Reef-safe sun cream matters when you are swimming over live coral.
Something on your feet is worth having. Sand gives way to broken coral without warning at the water's edge.

What the fare covers, and what to budget for separately.
The practical detail, and the answers people actually ask for.
Part of it was closed to fishing in 1974, the first protected area of its kind in the country, and a research station has been measuring the result ever since.
That fish inside the boundary grew larger and more numerous and then moved outward, so catches improved for the fishermen who had surrendered access.
Stocks inside fell within a few years and the surrounding catch fell with them; both recovered once the closure was enforced again.
Because it is a mobile bank of sand rather than a landform, and the seasonal switch in wind direction moves the whole thing to the far side of the island.
Its length and position depend on the month and on the tide. At high water it can be largely submerged, reappearing as the tide falls.
The resort day-use side: loungers, shade, showers, somewhere to eat and a maintained beach, along with access to the water.
No. It is shallow and close to shore, and the interesting ground is nearer in than most people assume.
Certain areas are closed to swimmers, contact with the living reef is prohibited, and wardens are on the water enforcing both.
